    Whadaya think?

    This I just made in Google Sketchup (I'm talking about smoothing edges!:oops:). Just playing with it... Only the Collada format was able to bring along its textures and colors. What do you think? I know the antennas will probably have to be transformed into 2D, and the face texture got all scrambled, but it's a very good (although incomplete) model - compared to its Blender source.

    COOL! :thumb:

    I'm sorry I missed the sense of your post, but now... Cheerio, pal! The model looks really good. As for the crushed face texture, don't worry. There is an easy way to fix it:
    https://www.youtube.com/watch?v=HHsRRLCAOm8
    Switch to parallel view, zoom in on the front of the face and draw a rectangle which is big enough to cover it. Switch to half transparent view so that you can see the face shining through the rectangle. Make a screenshot and import it in your favourite graphic program (e. g. Gimp). Crop the image to the dimensions of the rectangle. Import the original texture of the face and rescale and realign it so that it covers the front section of the face. Save the pic as .jpg or .png. Import it in SketchUp, put it on the rectangle in front of the face and project the texture on the face as shown in the vid. Repeat with the sides of the face.

    That's quite ok! It's the last official version, it'll take some (hopefully not long) time until 0.49 is out.

    Anything you can tell us about 0.49 that will make it so special?

    Or are you sworn to secrecy? :mrgreen:

    Anyone? Please?

    I was able to import my model to Google Sketchup and make it a bit "rounder":thumb::cool:, but I would like to go back to the Export Paper Model script for Blender. I really think that it worked fine so far, considering that no software can do what humans do (yet).
    My problem is, after exporting the paper model, all I get is plain black-and-white, uncolored templates. Yes, I know that you have to uncheck the "Pure Net", and I did, but all I've got was separate files, one for the "color", and the other for the net:curse:.
    When I say "color", I mean that the parts come filled with black, and no other color whatsoever (forget about textures). As I said before, I use Blender 2.65, and this is the best script I've found to unfold a paper model in Blender, but without the colors and textures...:cry:
    I did try to color the SVG files that the script generates, but for some unknown reason, I couldn't do it in Inkscape. I select the parts, change the filling color, and nothing happens... Although I could change the flaps' color! But I won't use them...:cry:
    Any comments? Please, not the "throw Blender away and do it all in Google Sketchup"...:eek: I really would like to solve the problem, but if things don't go anywhere, I'll change to Google.
    Thanks!

    It's no secret, take a look at http://wiki.inkscape.org/wiki/index.php/Release_notes/0.49 . I've been using nightly builds for some time. Some things that I particularly like:
    -it's way faster - the rendering has been rewritten, that's the main reason why 0.49 took so much time to develop (it's over a year since the last major version)
    -improved selection modes - select by object type, or by attributes (color for example)
    -improved snapping

    Rogerio: do you have some lights in your Blender scene? That may be it. Upload the svg file, I can take a look tomorrow; my guess is that the parts are in a different group than the tabs.

    Shed some light...

    I think I understood... I once read something about illumination, and now that you've mentioned it... it all makes sense! If the model is not lit for rendering, it all comes black! DARN:eek:! I'll give it a try right away!:thumb:

    For Revell-Fan: a face, at last

    Revell-Fan

    I'll bet you thought I didn't give your post the proper attention... HOHOHO... GOTCHA!sign1
    Thank you for both the projection class and the video, it was quite interesting and insightful. I need more practice, but here's a result. It's coming along nicely!
    I wanna learn about unfolding in Google Sketchup as well, and it seems a lot easier than Blender...
    Well, you know, maybe I like to suffer...:cry::rolleyes: Better to learn Blender and then go to something easier!sign1
    Here's Groizer-X face, still needing some corrections...

    Unfold your enthusiam...

    Imcold

    You were right:thumb:. All I had to do was to turn on the lights, and man, LET THERE BE LIGHT!:mrgreen:
    Here's a head test (literally:rolleyes:), with the SVG and PNG superimposed. No intelligence here, only automatic, but results do look VERY PROMISING.:thumb::cool:

    Hey, it looks great! (Anyway, you could have left the face the way it was and called it the "battle damaged version" :mrgreen::mrgreen::mrgreen:!)

    Hillarious, but it was too scrambled to look like something you could call face, even with some HEAVY battle damage...:cry::rolleyes: Well, now to learn about marking and unmarking seams...
    But I've got to tell you: I had to make some mods in the rear part, in order to make holes for the "rocket legs", and now, for this particular part, the Paper Model Export script doesn't want to work. I guess it's because I couldn't make the faces as a whole...:cry:
    So, maybe I'll have to unfold it in Google Sketchup, and I'll need your help. I guess there may have some videos in YouTube, right?
    Thanks!

    Internal issues...

    Do you guys know any threads or videos on how to desing an internal support structure (in Blender, prefferably...:twisted:)? Since we've been talking about the same model I'm trying to design, this question would come up sometime, anyway.:confused:
    I've been working on a model and I don't know how to make it balanced and internally formed. Of course, in the virtual world, it looks good, but when you print and build it, you have to deal with weight, gravity, and paper not being a stiffy material...:cry:
    Well, I think I'll redesign the "chest" and "waist" parts, to make them look better, but not much different from now. AND my model is a balance nightmare, because of thin, weirdly shaped wings, and things to add weight on the tip of them. Since I'm no engineer, I'm having a little trouble thinking about it, even after building some models and observing how they reinforce it internally.
    Just take a look at these two pictures, and you'll know what I'm talking about...:rolleyes:
